PPI::Token::Number - Token class for a number SYNOPSIS
$n = 1234; # decimal integer $n = 0b1110011; # binary integer $n = 01234; # octal integer $n = 0x1234; # hexadecimal integer $n = 12.34e-56; # exponential notation ( currently not working ) INHERITANCE
PPI::Token::Number isa PPI::Token isa PPI::Element DESCRIPTION
The "PPI::Token::Number" class is used for tokens that represent numbers, in the various types that Perl supports. METHODS
base The "base" method is provided by all of the ::Number subclasses. This is 10 for decimal, 16 for hexadecimal, 2 for binary, etc. literal Return the numeric value of this token. CAVEATS
Compared to Perl, the number tokenizer is too liberal about allowing underscores anywhere. For example, the following is a syntax error in Perl, but is allowed in PPI: 0_b10 TO DO
- Treat v-strings as binary strings or barewords, not as "base-256" numbers - Break out decimal integers into their own subclass? - Implement literal() SUPPORT
See the support section in the main module. AUTHOR
